In almost every territory, 20% of your prospects will generate 80% of your revenue. The problem is identifying which 20% before you've spent 80% of your time on the wrong accounts.
Start with your existing customers. Which ones generate the most revenue per rep effort? Map their characteristics: industry, size, years in business, location density, and — critically — what signals were present before they converted. That pattern is your ideal prospect template.
Tier 1: your highest-potential accounts
Map your territory against that template. Score every prospect on how closely they match your best customers. The top scorers are your Tier 1 — the 20% that deserves your best effort, your most personalised outreach, and your most senior resources.
Tier 1 gets a different strategy: more touchpoints, in-person visits, handwritten notes, executive sponsorship if relevant. You're not just prospecting; you're building a relationship from the very first contact.
Tier 2: medium-potential accounts
Tier 2 gets a lighter, automated touch: a four or five-email sequence, periodic phone attempts, event invitations. These accounts have potential but don't yet justify intensive effort. Some will graduate to Tier 1 when their situation changes.
Tier 3: minimum viable coverage
Tier 3 is everyone else. Minimum viable outreach — maybe an annual touchpoint. They're in your territory but not worth active investment right now. That can change, so keep them in your system.
The key insight: most sales teams treat every prospect the same way. Differentiation of effort based on potential is the single highest-leverage change most field sales teams can make.
Revisit your tiering quarterly. A Tier 3 account that gets acquired or hires a new operations director can become Tier 1 overnight. Build the habit of reassessment into your process.
